HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 189, 371 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 189, 371 is 7 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 189, 371 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 189, 371 is 7.
HCF(189, 371) = 7
HCF of 189, 371 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 189, 371 is 7.
Highest Common Factor of 189,371 is 7
Step 1: Since 371 > 189, we apply the division lemma to 371 and 189, to get
371 = 189 x 1 + 182
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 182 and 189, to get
189 = 182 x 1 + 7
Step 3: We consider the new divisor 182 and the new remainder 7, and apply the division lemma to get
182 = 7 x 26 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 189 and 371 is 7
Notice that 7 = HCF(182,7) = HCF(189,182) = HCF(371,189) .
